Step-by-step explanation:
y = -2/3 - 5x
rearranging,
y = -5x -2/3
comparing to the gradient-intercept equation
y = mx + c
m = -5
c = -2/3
Therefore, the slope of the line is -5
Answer: -5
Step-by-step explanation:
Because you know that y=Mx+p right?
So you just take the equation : -2/3-5x and you know that the number before x is m = the slope . Have a nice rest of your day :)

Answer:
If f(x)=g(x), the solution is x=-2
Step-by-step explanation:
We are given:
[tex]f(x)=3x+3\\g(x)= (-1/2)x-4[/tex]
We need to find the solution if f(x)=g(x)
Now solving for f(x)=g(x)
[tex]f(x)=g(x)\\3x+3=(-\frac{1}{2}x)-4\\3x+3=-\frac{1}{2}x-4\\3x+\frac{1}{2}x=-4-3\\\frac{3x*2+x}{2}=-7\\\frac{6x+x}{2}=-7\\\frac{7x}{2}=-7\\x=-7*\frac{2}{7}\\x=-2[/tex]
If f(x)=g(x), the solution is x=-2

with some functions, the value of the
dependent variable decreases as the value of the
independent variable increases. What is a real-world
example of this ?
Answer and explanation:
This is an example of negative correlation/inverse relationship between two variables. A negative correlation between two variables, independent and dependent variable, occurs when increase in one variable is associated with decrease in the other. In other words, the two variables tend to go in opposite direction.
The independent variable is the variable that causes a change in the dependent variable. For example, an increase in the independent variable in an inverse relationship will bring about a decrease in the dependent variable.
A good real world example is the increase in inflation and the decrease in purchasing power of money.
An equation for this could be
Y=-0.2(x)
Where y is dependent variable purchasing power and x is independent variable inflation

Write an equation in the form y=mx for the proportional relationship that passes through the points (2, -15) and (6, -45).
Answer:
Y=-15/2x
Step-by-step explanation:
The equation of line in the form y=mx is y=-15/2x
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given coordinates:
(2, -15) and (6, -45).
Now, slope for the equation
slope= [tex](y_2 - y_1)/ (x_2- x_1)[/tex]
slope= (-45 - (-15))/ (6 - 2)
slope= (-45 + 15)/ 4
slope= -30/4
slope= -15/2
Hence, the equation of line in the form y=mx is y=-15/2x

Isosceles triangle:It is a triangle with two equal angles or two equal side.Angles opposite to the equal sides of an isosceles triangle are also equal.Angle bisector is perpendicular to the base in an isosceles triangle.What is angle bisector?"It is a ray/line that divides an angle into two equal parts."
From figure,
BD is perpendicular to the base AC.
Since BD is an angle bisector,
⇒ 4x - 8 = 20
⇒ 4x = 20 + 8
⇒ 4x = 28
⇒ x = 28/4
⇒ x = 7
Therefore, the range of the values for x would be,
6 < x < 8.

Step-by-step explanation:
x² + 3x + 7 = 5 ( subtract 5 from both sides )
x² + 3x + 2 = 0 ← in standard form
(x + 2)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x ( zero product rule )
x + 2 = 0 → x = - 2
x + 1 = 0 ⇒ x = - 1
--------------------------------------------------------------
x² - 2 = - 2x² + 5x ( subtract - 2x² + 5x from both sides )
3x² - 5x - 2 = 0 ← in standard form
(3x + 1)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
3x + 1 = 0 ⇒ 3x = - 1 ⇒ x = - [tex]\frac{1}{3}[/tex]
x - 2 = 0 ⇒ x = 2
------------------------------------------------------------
(x + 3)² + 4x = 0 ← expand left side using FOIL and simplify
x² + 6x + 9 + 4x = 0
x² + 10x + 9 = 0 ← in standard form
(x + 9)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x + 1 = 0 ⇒ x = - 1

Students make 97.5 ounces of liquid soap for a craft fair. They put the soap in 7.5-ounce bottles and sell each bottle for $5.50$. How much do the students earn if they sell all the bottles of liquid soap? Explain.
Answer:$71.50
Step-by-step explanation:
Hello!
So first you want to find out how many bottles of soap you can make
To do that you want to divide how many ounces you have by how many ounces it takes to make 1 bottle
97.5 / 7.5 = 13
So you know you can make 13 bottles of soap
So now you want to multiply the number of bottles of soap that can be made by the amount of money you can make per bottle
13 * 5.50 = 71.50
So you know that the students can make $71.50

I hope that this helps you, have a wonderful day!
The best estimate from the option is 14,000 since 14,000 is the nearest value from the option to 12763.
Given,
18 x 709
We need to find the best estimate.
How do multiply numbers?We need to multiply each number of one number with the other number and add them to get the product.
Example:
21 x 34 =
21 x 3 = 63
21 x 4 = 84
2 1
x 3 4
84
+ 63
71 4
We have,
18 x 709
We can write it as:
709 x 18
709 x 8 = 5672
709 x 1 = 709
709
x 18
5672
+ 709
12762
Thus the best estimate from the option is 14,000 since 14,000 is the nearest value from the option to 12763.
